LIFE-BOAT.

incassa Speccation of Letters Patent.

Patented July 21, 1914.

Application filed April 11,1914. Serial No. 831,223.

To all whom, t may concern Be it known that l, lvlioHAL RAZNIAK, a subject of the Emperor of Germany, residing at Strathcona, Alberta, Canada, have invented certain new and useful lmprovements in Life-Boats, of which the following is a specification.

rlhis invention relates to certain new and useful improvements in life boats.

rlhe primary object of this invention is lto provide a. completely decked motor-driven life boat having the passenger compartment swingingly ournaled and rendered incapable of overturning under any possible circumstances regardless of the position of the exterior floating hull.

la still further object is to provide a tubular floating hull completely inclosing a journaled passenger compartment carrying a Ventilating system and a motor propelling plant for the craft.

A still further object is to provide a tubular floating boat casing with a constantly upright passenger compartment suspended therein, said casing provided with entrance openings and with racks, whereby persons may be rescued from drowning while the occupants may properly steer the boat and manually operate a propelling motor and a Ventilating motor therefor.

Another object is to provide a tubular boat casing freely revoluble when floating in the water and being accessible for exit and entrance in any position of the casing while the same is provided with a combined power and steering propeller actuated interiorly of the casing.

1With these general objects in view and others that will appear as the nature of the invention is better understood, the same con-v sists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several vienne-Figure 1 is a side elevation of the device. Fig. 2 is a vertical transverse sectional view'upon line 2-2 of Fig. 3, looking in the direction of the arrows. Fig. 3 is a vertical longitudinal central sectional view of the device, and,

4 is an enlarged detail view of the propeller steering mechanism.

Referring more in detail to the drawings,

a tubular hull 10 is provided with door windows 11 in the conical ends 12.thereof and with usual windows 13 positioned around the casing and also provided with doors 14 in the main portion of the casing while loops 15 are provided at :each end for attachment to hoisting means [for the boat. The exterior of the boat is j provided with a rack or net 16 extending` substantially over the entire surface there- ,of and adapted for the convenience of persons in the water in assisting them to enter Ikthe life boat.

A passenger compartment 17 is mounted fwithin the casing and journaled at its op- Iposite ends in bearings 18 in the form of 'perforations extending through the ends of the casing 10, said compartment being subgstantially boat-shaped and mounted within the casing upon antifriction rollers 19 while racks 20 project upwardly from the opposite sides of said compartment.

The forward end v`o'rbow 21 of the boat is provided with a Ventilating tube 22 projecting through the journaling means for the casing and having an opening end 23 within the casing and whereby fresh air may enter the same, while a sliding damper 24 controls `the, admission of air therethrough. The vstern 25 of the boat is provided through its giournaltube 29 with an air exit tube 26y ,fleading interiorly of the casing 10` to an air expelling fan 27 operable by means of crank arms 28 and whereby as will be evident, the yrotating of said arms actuates the fan to expel air through the outlet tube 26 and draw fresh air within the casing through lthe entrance tube 22.

` The closed tube 29 extending from the rear end of the passenger compartment and being thestern journalingl means therefor in' the bearing 18, accommodates the eXit tube 26` while it also has journaled therein a shaft 30 operable by a gear and pinion connection by the crank handles 28 in the manner illustrated while its outer end is provided with a pinion 31 meshing with a smaller pinion 32 upon the upright shaft 33, which latter is journaled in an upright tubular casing 34 depending from and communicating with the interior of the casing 29. The bottom of the tubular casing 34 is provided with a receptacle 35 having a segment 36 substantially centrally journaled therein upon the bearing 37 and provided with an upwardly-extending wheel 45.

toothed flange or rack 38 adapted for meshing engagement with a pinion 39 carriedb-y the lower end of a sha-ft 40, the upper` end of which shaft is operatively connected by means of pinions 4l and shafting 42 with a pinion 43 upon a turn shaft 44 adapted to be operated by means of a hand steering Said'segment 36 is provided with an upright post 46 acting as a journal bearing for the shaft 47 of a propeller blade 48 while apinion 49 upon said shaft meshes with a similar pinion 50 upon the shaft 33 and whereby, as will be evident, a turning of the crank handles 28 operates to revolve the propeller and furnish motive power therefor through the pinions and shafts described.

The complete operation of the device is believed to be apparent from the above detailed' description. By operating the crank members 28, the propeller 48 is turned for imparting movement to the boat through the walter, While simultaneously therewith the air expelling` circulating fan 27 is set in motion which draws in fresh air to the boat inclosure.

The steering wheel 48 is actuated for steering they craft by a rotation of the segment 36 which thereby laterally shifts the propeller blade 48 to the requisite side for steering in the desired direction. The suspending of the passenger compartment 17 within t-he casing allows the action of the waves and the elements to turn the casing over without in any manner affecting the equilibrium of such compartment, which by the force of gravity is held suspended in its normal upright position. The positioning of the doors and 2windows as described, allows free entrance and exit to the interior of the casing, no matter which side of the casing is positioned above the water line while the encircling rack 16 facilitates persons in the water in retaining their hold upon the boat until the rescue of su'ch persons is effected.

While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is `nevertheless to be understood that various forms and modifications thereof may be had without departing from the spirit and scope of the invention as claimed.

Having thus described the invention, what I claim as new is v I. A device of the class described comprising in combination with a tubular hull having a journaling perforation through the stern end thereof, a tubular casing journaled in said perforation, a downwardly-extending casing upon said tubular casing and havnected with said rack for shifting said segment in the steering operation.

2. A device of the class described con prising a tubular hull having conical ends provided with journal perforations, a boatshaped passenger compartment within said hull, oppositely-projecting tubes secured to said compartment and journaled in said perforations, air conduits extending through each of said tubes and communicating with the interior of the hull, an air expelling fan journaled positioned within one of said conduit-s, an extension upon one of said tubes, a laterally-shiftable propeller blade journaled in said extension, a crank means, operative means between said crank -means and said propeller and fan, and steering means within said passenger compartment adapted for laterally shifting said propeller.

In testimony whereof I affix my signature in presence of two witnesses.
